Freckles are clusters of tanned circular spots on the skin. These are more prominent on the skin of fair people and tend to develop on the skin in a random manner. These can get aggravated owing to exposure to sun. Freckles set in when there is concentration of melanin under the skin and are of the size of head of nails.

The color and distribution of freckles is mostly uniform, and these may have yellow, red, black or brown color. Their color gets dark during summers and lightens during winters. Freckles do not signify any serious skin problem, but tend to be mistaken for moles in many cases. While these do not lead to skin cancer, the disease may masquerade itself as freckles. Certain treatment methods can help in lightening or complete elimination of freckles.
